If you choose, Bluetooth is more expensive, but if the computer has Bluetooth function, you can save an adapter. Compared with Bluetooth mouse, it only consumes a little electricity. Of course, a well-made mouse also saves electricity. The advantage of 2.4G ordinary wireless mouse is stability, and the probability of disconnection is much smaller and cheaper than that of Bluetooth mouse. But you can't get rid of the adapter, no matter how big it is, you have to bring it. Most 2.4G wireless mice are one adapter to one mouse. When you put the mouse on another computer, the adapter should follow. And Bluetooth will be much more convenient.
Let's look at photoelectricity, laser and blue shadow. These are easy to understand, that is, the positioning light emitted from the bottom of the mouse. The photoelectric one is the one with red light at the bottom. Blue shadow is also a kind of photoelectricity, but the light is blue, which turned out to be a gimmick. The laser mouse uses a tiny red laser beam, so it is difficult for the naked eye to see its red light. The advantage is that laser positioning is more accurate, but the cost is more expensive.
Suggestions are as follows: 1, laser is better than photoelectric, and blue shadow is gimmick equals photoelectric.
2. Bluetooth consumes more electricity than ordinary 2.4G wireless mouse, so it can only be equipped with Bluetooth-enabled devices, unless it is equipped with a universal Bluetooth adapter, which is relatively more likely to be disconnected.
Now the wireless mouse technology is very mature, which usually takes 3 ~ 6 months. High-end products can be 1 year or more. Logitech and Microsoft are better than domestic brands, mainly in positioning.
Teach you a trick to tell whether the mouse is good or bad: make a circle with the mouse in drawing software, and the more round the circle drawn, the better the mouse.
